The invention relates to both the individual stereoisomers of the formula I which are possible and also to mixtures of these isomers

The new types of heterocyclic compounds of the general formula I are obtained by the present invention when aryl isocyanates of the general formula II

    Q--NCO                                                     II

in which,

Q is defined as above, react with carboxylic acids or their esters of the general formula III ##STR8## in which m, X, R¹, R², R³ and R⁴ are defined as above, and R represents hydrogen, a (C₁ -C₄)-alkyl group or an active ester, in accordance with method A, optionally in the presence of an acid acceptor and optionally in the presence of a diluent.

The invention also provides a method B for preparing compounds of the formula I by means of a reaction between compounds of the general formula IV ##STR9## in which, X, R¹, R², R³ and R⁴ are defined as above and Y═O, S or NH; and a halide of the formula V, VI or VII,

    R.sup.11 --Z                                               V

in which Z is a chlorine, bromine or iodine atom and R¹¹ and R¹⁶ are defined as above.

The invention also provides a method C for preparing compounds of the formula I, which is explained in the following; wherein m, X, R¹, R², R³, R⁴ and Q are defined as above.

In this case, a compound of the formula III, in which R═H or a (C₁ -C₄)-alkyl group, reacts with phosgene or a phosgene substitute, wherein initially compounds of the formula VIII are produced and these then react with compounds of the formula IX to give compounds of the formula X, ##STR10## prior to converting a compound of the formula X into compounds of the formula I by ring-closure.

The invention also provides a method D for preparing compounds of the formula I, which is explained in the following, wherein m, X, R¹, R², R³, R⁴ and Q are defined as above and wherein a compound of the formula II reacts with a compound of the formula XI, optionally in the presence of an acid acceptor and optionally in the presence of a diluent, that compounds of the formula XII are thereby produced and that the compounds XII thereby obtained are then hydrolysed and converted into compounds of the formula I by ring-closure. ##STR11##

In the case of method A, when R=alkyl, the reaction is performed in an inert organic solvent, for example in an aromatic solvent such as toluene or chlorobenzene, a halogenated hydrocarbon such as chloroform or methylene chloride, an ether such as diisopropyl ether or in acetonitrile or dimethyl-formamide, optionally base-catalysed, at temperatures between 20° and 125° C. Organic bases are preferably used as bases, for example organic amines such as triethylamine or pyridine.

In the vent that R═H, the reaction is performed in water as a solvent or, preferably, in a two-phase water/organic solvent system. Particularly preferred is the method of working in which a compound of the formula III, optionally a salt of III, is added to water together with an inorganic base, for example an alkali metal or alkaline earth metal hydroxide, carbonate or hydrogen carbonate, such as sodium hydroxide or potassium carbonate, or together with an organic base such as, for example, an organic amine such as triethylamine, and then compounds of the formula II, dissolved in an inert solvent such as, for example, toluene, chlorobenzene or chloroform, are introduced. The reaction mixture is then maintained at temperatures between -40° C. and +50° C., preferably between -10° C. and +10° C., for several days, preferably between 3 and 50 h.

The aqueous phase is then adjusted to a pH between 1 and 3 with acid, preferably an inorganic acid such as aqueous hydrochloric or sulphuric acid. The urea derivatives produced in this way (see compounds X) are then cyclised at temperatures between 50° and 100° C., optionally in the presence of an acid such as hydrochloric acid and/or formic acid, or optionally by conversion into an ester (R=alkyl or active ester, e.g. an O-succinimide ester or anhydride ester) using known methods (see Houben-Weyl, "Methoden der organischen Chemie", vol. XXV/1 and XXV/2 (1974)).

Compounds of the formula II are known or may be prepared by analogy with known methods, see Houben-Weyl, "Methoden der organischen Chemie", vol. VIII, p. 120 (1952); Houben-Weyl, vol. IX, pp. 875, 869 (1955); EP-B1 0 070 389; U.S. Pat. No. 4,881,967; EP-A1 322 401; U.S. Pat. No. 3,495,967; EP-A-2 300 307; EP-A2 349 832.

Amines of the formula III are known and may be prepared by analogy with known methods; see here, for example, M. Sekiya et al., Chem. Pharm. Bull. 31 (1) 94 (1983); J. M. Cassal. A. Furst, W. Meier, Helv. Chim. Acta, 59 (6) 1917 (1976); S.-K. Tsui, J. D. Wood, Can. J. Chem., 57 (15) 1977 (1979); M. Sekiya et al., Chem. Lett., (2) 231 (1982).

Finally, it was found that the new types of heterocyclic compounds of the general formula I have remarkable herbicidal properties.

The invention therefore also relates to herbicidal compositions which contain an effective amount of a compound of the formula I and a carrier. Carriers are advantageously surface active substances or solid or liquid diluents.

The invention also relates to a process for controlling weeds in which a herbicidally effective amount of a compound in accordance with formula I is applied to the weeds or their surroundings (before or after germination).

DETAILED DESCRIPTION OF THE INVENTION CHEMICAL EXAMPLES Example 1 ##STR12##

A mixture of methyl 2-piperidinacetate (1.94 g, 0.1 mol), triethylamine (50.0 mg, 0.5 mmol) and toluene (30 ml) is prepared and to this is added, dropwise, 4-chlorophenyl isocyanate (1.40 g, 0.009 mol) dissolved in toluene (20 ml). The reaction mixture is maintained under reflux for 10 h and then washed with 3×10 ml of 10% strength aqueous hydrochloric acid and 3×10 ml of water, dried over sodium sulphate and filtered. After concentrating the filtrate by evaporation, the residue is dissolved in methylene chloride and reprecipitated from petroleum ether. 2.09 (75% of theoretical) of 5-(4-chlorophenyl)-4,6-dioxo-1,5-diazabicyclo-[4.4.0]-decane with a melting point of 139°-141° C. are obtained.

Example 2 ##STR13##

A mixture of 5-(4-chloro-2-fluoro-5-hydroxyphenyl)-4,6,-dioxo-1,5-diazabi cyclo-[4.4.0]-decane (3.13 g, 0.01 mol), potassium carbonate (6.95 g, 0.05 mol), propargyl bromide (1.78 g, 12.0 mmol) and acetonitrile (60 ml) is stirred for 72 hours at room temperature. The reaction mixture is acidified to pH 2 with 5% strength aqueous hydrochloric acid and then extracted with 3×15 ml of ether. The ethereal layer is dried over sodium sulphate and then filtered. After evaporating off the solvent, the residue is purified using silica gel chromatography.

3.11 g (89% of theoretical) of 5-(4-chloro-2-fluoro-5-propargyloxyphenyl)-4,6-dioxo-1,5-dia zabicyclo-[4.4.0]-decane are obtained as a colourless oil.

Formulations

Appropriate formulations using compounds of the formula I can be prepared by conventional methods, in the form of powders, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates, etc. Many of these forms may be applied directly. Sprayable preparations may be diluted with appropriate media and applied by spraying at a rate of between a few and a few hundred liters per hectare. Highly concentrated preparations are mainly used as intermediates for other formulations. The formulations contain, in very approximate terms, between 0.1 and 99 wt. % of active substance(s) and at least one member from the group a) 0.1 to 20% of surface-active substance and b) about 1 to 99.9% solid or liquid diluents.

Active substance plus at least one surface active substance or on      diluent = 100 wt. %                                                      

Smaller or larger amounts of active substance may naturally be present, depending on the intended application and the physical properties of the compound. Larger ratios by weight of surface-active component to active substance are sometimes desirable and are achieved by incorporation in the formulation or by mixing in a container.

Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers" (Handbuch der Verdunnungsmittel und Trager staubformiger Insektizide), 2nd ed., Dorland Books, Caldwell, N.J., but other solids, either mined or industrially produced, may also be used. In the case of wettable powders, the more absorbent diluents, and in the case of dusts, the more dense diluents, are preferred. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide" (Losemittelfuhrer), 2nd ed., Interscience, New York, 1950. Less than 0.1% is preferred for concentrated suspensions. Concentrated solutions are preferably resistant to phase separation at 0° C. "McCutcheon's detergents and emulsifiers annual" (McCutcheon's Jahrbuch der Detergentien und Emulgatoren), MC Publishing Corp., Ridgewood, N.J., and Sisely and Wood, "Encyclopedia of Surface Active Agents" (Enzyclopadie der oberflachenaktiven Stoffe), Chemical Publishing Co. Inc., New York, 1964, contain lists of surface-active substances and the applications for which these are recommended. All formulations may contain relatively small amounts of additives to reduce the formation of foam, or to inhibit caking, corrosion or the growth of microorganisms, etc.

Methods for producing such preparations are well known. Solutions are prepared by simply mixing the constituents. Finely powdered solid preparations are obtained by mixing and, usually, milling, for example in a hammer mill or a jet mill. Suspensions are obtained by wet milling (see e.g. Littler, U.S. Pat. No. 3,060,084). Granules and pellets can be prepared by spraying the active substance onto pre-shaped, granular carriers or by agglomeration. For this, see J. E. Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, p. 147 et seq. and "Perry's Chemical Engineer's Handbook" (Perry's Handbuch des chemischen Verfarhrenstechnikers), 5th ed., McGraw Hill, New York, 1973, p. 8-57 et seq.

Sodium alkylnaphthalene sulphonate 2%

Low viscosity methyl cellulose 2%

Diatomaceous earth 46%

The constituents are mixed, coarsely crushed in a hammer mill and then milled in a jet mill so that virtually all the particles have a diameter of less than 10 μm. The product is then re-mixed before packaging.

Example C

Granules

Wettable powder from example B 5%

Attapulgite granules 95%

(USS 20-40 mesh; 0.84-0.42 mm)

A slurry of wettable powder with a 25% solids content is sprayed into a double cone blender. The granules are then dried and packaged.

Sodium alkylnaphthalene sulphonate 1%

Calcium/magnesium bentonite 59%

The constituents are mixed, milled in a hammer mill and then moistened with approximately 12% water. The mixture is extruded to form cylinders with a diameter of approximately 3 mm, which are cut into pellets with a length of approximately 3 mm. These can be used directly after drying. The dried pellets, however, can be crushed so that they pass through a USS no. 20 sieve (mesh 0.84 mm diameter). The granules remaining behind on USS sieve no. 40 (0.42 mm mesh diameter) can be packaged for use, while the fine fractions are returned.

N,N-dimethylformamide 9%

Attapugite granules 90%

(USS sieves 20 to 40)

The active substance is dissolved in the solvent and the solution is sprayed onto de-dusted granules in a double cone blender. After spraying the solution in, the mixer is run for only a short time, after which the granules are packaged.

Example F

Granules

5-(4-chlorophenyl)-4,6-dioxo-1,5-diazabicyclo-[4.4.0]-decane 80%

Wetting agent 1%

Crude lignosulphonate (with 5 to 20% of 10% natural sugar)

Attapulgite clay 9%

The components are mixed and milled until they pass through a 100 mesh sieve. This material is then introduced to a fluidised bed granulator, where the air current is adjusted so that the material is readily whirled up and wherein a fine jet of water is sprayed onto the swirling material. Fluidisation and spraying are continued until granules of the desired size are obtained. Spraying is then discontinued, while fluidisation on the other hand, optionally with the introduction of heat, is continued until the water content has fallen to the desired value, generally less than 1%. The material is then withdrawn and screened to the desired size range, usually 14 to 100 mesh (1410 to 149 μm), when it is packaged for use.

Biological examples

Trial results show that the compounds according to the present invention are effective herbicides. They are suitable for broad-band control of weeds before and after germination in areas where the whole vegetation is intended to be kept under control, for example in the vicinity of industrial storage areas, car parks, drive-in cinemas hoardings, roads and railway structures. Many of the compounds are also suitable for selective weed control when cultivating, for instance, rice, wheat, barley, maize, soy beans, sugar beet and cotton.

The amount of compounds according to the present invention to be applied depends on numerous factors including its use as a selective or universal herbicide, the particular agricultural crop, the type of weed to be controlled, the weather and climate, the formulation selected, the method of application, the amount of foliate vegetation etc. In general, the compounds should be applied in amounts between 0.001 and 20 kg/ha, wherein the smaller amounts are suitable for lighter soils and/or soils with low concentrations of organic substances or in the event that only short residence times are required such as in the case of herbicides for fallow land.

The compounds according to the invention may be used in combination with any other commercially available herbicide.

The herbicidal properties of the compounds according to the present invention were discovered in a series of hothouse trials. The test method and results are given in the following. ##STR24## Test Method

Seeds of digitaria spp, echinochloa crus-galli, setaria feberii, avena fatua, bromus secalinus, abutilon theophrasti, ipomoea spp., xanthium pensylvanicum and Sorghum-Knollen were used and treated, before germination, with the trial chemical dissolved in a non-phytotoxic solvent.

In addition, these weeds were treated with a preparation specified for soil and for foliage. The plants were 2 to 18 cm tall at the time they were treated. The treated plants and the control plants were kept for 16 days in a hothouse, then all specimens were kept with the control plants for 16 days in the hothouse, after which all specimens were compared with the control plants and the effect of the treatment was assessed visually. The evaluations summarised in Table A are based on a numerical scale from 0=no damage to 10=complete destruction.

The symbols alongside the numbers indicate the following:

C=chlorosis/necrosis

B=burning effect

H=deforming effect

E=germination inhibited

G=growth stimulated
